16. A steel ball of mass 0.50 kg, moving with a velocity After the collision 2.0 m/s, strikes a second ball of mass 0.30 kg, initially at rest. The collision is a glancing one, causing the first ball to be Before the collision deflected by an angle of 30', with a speed of 1.50 m/s. Determine the velocity of the second ball after the collision, giving both its speed and direction [10]
